I do believe that's a rebadged Mazda Demio - Z development of their B engine - ask a Mazda mechanic.

I will say it is a non interference engine in the z tech. My research and conversations with ford mechanics say that the z tech Mazda ford engine is the same in the contour/mystique ford escort zx2 and some Mazda labelled vehicles. If info and research says the escort or the countour is non interference then I would believe the same with the Focus.

looking for an engine no on a mazda 1992 121,were is it locoteded on engine

The Mazda Rx7 has the Wankel Rotary Engine in it

engine size is found on the engine, but all Mazda engines in the b and z family have the imprint of DOHC on the rocker-cover when they are dohc

if you find an imprint of b6-XX-XX then you have a 1.6 and if dohc is found on the rockercover then it is a 1.6 dohc.

if you see b8, then that is always a 1.8l SOHC engine
